This scatter plot visualizes the Iris dataset, mapping petal length and width for individual specimens while coloring each point by species (setosa, versicolor, or virginica). The visualization renders circles in an SVG using D3 v6, with scales created via `d3.scaleLinear` and axes generated by `d3.axisLeft` and `d3.axisBottom`. Data is loaded asynchronously from a remote CSV using `d3.csv`, and the code also reads sepal measures into each row but does not use them for the plotted positions.
